Cookie Policy
Tutor Volt Ltd | Last updated: 15 February 2026
1. Introduction
This Cookie Policy explains what cookies are, how Tutor Volt Ltd ("we", "us", "Tutor Volt") uses them on our platform at tutorvolt.ai and tutorvolt.co.uk (the "Platform"), and what choices you have.
We keep our use of cookies to a minimum. We do not use advertising cookies, tracking cookies, or third-party marketing cookies. The cookies we use are necessary for the Platform to function or to help us fix technical problems.
2. What Are Cookies?
Cookies are small text files that are placed on your device (computer, tablet, or phone) when you visit a website. They are widely used to make websites work, to remember your preferences, and to provide information to the site owner.
Cookies can be:
- Session cookies -- These are temporary and are deleted when you close your browser.
- Persistent cookies -- These remain on your device for a set period or until you delete them.
- First-party cookies -- These are set by the website you are visiting (in this case, Tutor Volt).
- Third-party cookies -- These are set by a different website. We use very few of these, and only for essential error tracking.
